11.54 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes one translucent brown moonstone, presented and certified by The Natural Gemstone Company, with a measured weight of 11.54 carat. The stone is fashioned in an oval shape with dimensions of 15.37 x 12.30 x 8.17 mm, and it is finished with a traditional cabochon cut that preserves the material and showcases its internal light effects. Clarity is graded as very slightly included, evaluated at eye level, a grade that indicates minimal internal features which do not detract from overall appearance when mounted. Color intensity is assessed as medium, providing a balanced brown tone that is neither too dark nor overly pale, and the surface displays an excellent polish that produces a uniform and reflective dome. No enhancement has been applied to this specimen, and the documented origin is Ceylon Sri Lanka.

The cabochon cut and the translucent body of this moonstone combine to emphasize its characteristic optical behavior, notably a soft sheen that may shift subtly with changes in viewing angle and illumination. The dome profile produces a smooth light return, and the medium color intensity allows light to transmit and interact within the stone without overwhelming its lighter internal reflections. Very slight inclusions, when present, are internal and typically contribute to the gem character rather than detract from it, especially in hand settings where the cabochon silhouette reads as a single luminous surface. The excellent polish ensures low surface scattering and a clean surface appearance, which is important for stones intended for rings, pendants, or brooches where tactile interaction may be frequent. Proportions and thickness are appropriate for secure mounting, and the generous table area offered by the oval form provides a stable visual focal point in a variety of design styles.

Provenance and treatment status are significant for evaluation and long term value, and this moonstone is supplied without any enhancement, with a documented origin of Ceylon Sri Lanka. Ceylon is well known for producing moonstones with refined color and desirable optical effects, and sourcing from this region supports predictable material characteristics for use in bespoke or production settings. Care recommendations for this material include avoiding prolonged exposure to strong chemicals and repeated thermal shock, cleaning with warm soapy water and a soft brush when needed, and refraining from ultrasonic or steam cleaning methods which can risk internal stress in translucent feldspar material. For mounting, consider protective settings such as bezels for rings intended for daily wear, while prong settings may be appropriate for pendants and earrings with lower impact exposure. The Natural Gemstone Company provides this detailed description to assist in appraisal, design planning, and selection, and to confirm that the presented attributes reflect direct assessment of this specific moonstone.
